Abstract
The utility model discloses a spring pre-tightening mechanism, which is characterized in that a connecting flange (10) and an interface flange (7) are respectively connected with a cylinder (9); and a connecting baffle (11) is connected with a hollow shaft (4), a spring assembly (8) and a sliding baffle (3) are respectively sleeved on the hollow shaft (4), the sliding baffle (3) is connected with an end cover (1) through threads, a round nut (2) is also arranged on the rotating sliding baffle (3), and the end cover (1) is connected with the interface flange (7) through a bolt (5) and a nut (6). The connecting flange (10) is provided with a hole (13), and the end face of the hole (13) is provided with a concave surface (14). The center of the connecting baffle (11) is provided with a hole (12). The end cover (1) is connected with the interface flange (7) through the bolt (5) and the nut (6). The spring pre-tightening mechanism has a simple structure, can be easily combined with other components, and can work reliably. Moreover, the spring pre-tightening mechanism can provide sufficient pressure for tight combination of an aluminum guide rod and a bus during operation of an anode bus lifting framework, so as to ensure normal production.
Description
Technical field
This practicality relates to the spring pretightening mechanism of a kind of aluminum electrolysis industry in the operating process of positive bar lift frame.
Background technology
At present, when in Aluminum Electrolysis Production, needing to promote bus, need the positive bar lift frame to assist and finish.The effect of positive bar lift frame is the anchor clamps on the cylinder ventilation promotion piston rod drive positive bar lift frame that makes on it, make aluminium guide bar compress bus, clamp the capsule anchor clamps of aluminium guide bar then with tool to open, at last to lift energising beginning to promote bus.In the process that bus promotes, because the reactive force of anchor clamps upper cylinder, aluminium guide bar and bus are in fit-state all the time.After the bus lifting puts in place, tighten the capsule anchor clamps with instrument, aluminium guide bar and bus are fit together closely.Afterwards, close source of the gas, make anchor clamps be in relaxed state, at last the positive bar lift frame is hung electrolyzer, finish bus and promote action by return spring.If the cylinder supply gas pressure is not enough or die in operating process, will cause and fit bad between aluminium guide bar and the bus or throw off, directly influence is kept the safety in production.
Summary of the invention
The technical problem that this practicality will solve is, a kind of simple in structure and reliable spring pretightening mechanism is provided, in the operating process of positive bar lift frame, for aluminium guide bar and bus fit tightly the pressure that provides enough, fit bad between aluminium guide bar that prior art exists and the bus or throw off to overcome, directly the influence deficiency of keeping the safety in production.
This practicality is by the following technical solutions: joint flange and flange respectively with cylindrical shell; Connect baffle plate and be connected with tubular shaft, spring assembly, slide damper overlap respectively with tubular shaft on, slide damper is connected with end cap by screw thread, round nut in addition on the rotational slide baffle plate, end cap is connected with flange by screw bolt and nut.
Joint flange is porose, has concave surface on its end face.
Connect the central porose of baffle plate.
Joint flange and flange respectively with cylindrical shell for being welded to connect.
Connect baffle plate and tubular shaft for being welded to connect.
End cap is connected with flange by bolt, nut.
This utility structure is simple, with other member combined and instants, reliable operation, in the operating process of positive bar lift frame, for aluminium guide bar and bus fit tightly the pressure that provides enough, guarantees to produce and normally carries out.
